STOVEPIPE- CQUPLING.

SPECIFICATION forming part of Letters Patent N0. 628,882, dated July 11,1899.

Application filed \Tune 2, 1898. Serial No. 682,383. (No model.)

Stovepipe-Coupling, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedStovepipe-coupling which is simple and durable in construction andarranged to permit of conveniently, quickly and securely fastening theends of adjacent stovepipe together to hold the pipe perfectly straightand rigid without requiring riveted joints, supporting screw-hooks, orothersupports.

The invention consists of novel features and parts and combinations ofthe same, as Will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

' in which similar characters of referenceindicate corresponding partsin all the figures.

Figure l is a front elevation of the improvement as applied and withparts in section. Fig. 2 is an enlarged sectional plan view of theimprovement. elevation of the tightening device for the clamping-band ofthe coupling. Fig. 4 is a sectional plan view of the same onthe line 4 4in Fig. 3. Fig. 5 is a side elevation of the clamping-band. Fig. 6 is aplan View of the same.

The improved pipe-coupling is provided with a band A, swaged in its bodyportion A, so as to show in cross-section an ogee form, the top andbottom edges A being bent inward, as is plainly indicated in thedrawings. The ends-of the band A are formed with external flanges A Astanding at a slight angle to each other, as is plainly indicatedinFigs. 2 and 5, and the said flanges are fitted into correspondinggrooves B B respectively, in the bars B B, preferably made of malleableiron and securely fastened in place on the ends of the band by hammeringthe bars to close them firmly onto the flanges A and A On the bar B isformed a longitudinally-extending pin B formed with an internalscrewthread and fitted to slide in a tube B secured to the other bar B.A screw 0 screws in the Fig. 3 is an enlarged front threaded pin B andis adapted to abut with its head Oagainst the outer end of the tube B sothat by turning the screw the diameter of the band A can be increased ordecreased, so as to first loosely place the band onto the ends of thepipe-sections D D, as is plainly indicatedin Fig. 1, and then byscrewing up the screw 0 the endsof the band A are drawn tightly togetherto securely clamp the band on the jointed pipe-sections. In doing so.the swaged body portion A of the clamping-band A fits on a correspondingswage on the small end of the pipe-section, and the bent edges A of theclamping-band fit snugly upon the pipe to prevent any escape of thesmoke or gases from the joint between the two sections.

By having the flanges A and A standing slightly at an angle to eachother sufficient flare is given to the band to bind tightly on the largeand small end of the pipe-sections D and D. (See Fig. 1.)

It is evident that by having the connection between the ends of the bandA adjustable, as described, the band will readily compensate forpipe-sections of slightly larger or smaller diameter.

Having thus fully described my invention, I claim as new and desire .tosecure by Letters Patent 1. A stovepipe-coupling provided with a band,and a fastener for the ends of the band, and comprising two memberssecured to the band ends, one member being provided with a tube forreceiving a threaded pin on the other member, and a screw screwing insaid threaded pin, the head of which abuts against the outer end of thetube, substantially as shown and described.

2. A stovepipe-couplin g, com prisin ga band having its endsformed withouter flanges, fastener-bars having slots for receiving the saidflanges, a tube on one of thebars, an internally-threaded pin on theother bar and fitted to slide in the said tube, and a screw screwing insaid pin, its head being adapted to abut against the outer end of thetube, substantially as shown and described.
